Stone Mountain near Atlanta, GA has a skyride which is a gondola suspended from a cable that takes people to the top of Stone Mountain as well as back down.
Using the First Law of Thermodynamics, what would be the most efficient way to design this ride?
Discuss if this might be used to generate rather than use electrical energy. If so, what would be required? If not, why not?
Consider the circuit made of a R = 100 resistor, voltage source V , and fuse F. The fuse breaks if the instantaneous current in the circuit reaches 1 A. Which of the following voltage sources can be used in the circuit without breaking the fuse?
